Thanks to annotations, codes and numbers written on the mounts, but also to signs within the images, the locations of one fifth of J. B. Jackson’s slides kept by the UNM can be identified. This proportion is too small to precisely track Jackson’s routes and stopping places. However, it is sufficient to discover in what direction he drove and how he photographed along the roads, most often without staying.
Annual maps of J. B. Jackson’s slides have been designed on the basis of these annotations. These maps allow us, among other things, to learn that Jackson traveled through California, the Rocky Mountains, and High Plains, but also through New England and the Deep South during the sixties. They show that mainly from 1966 to 1979 he crossed, discovered and sometimes visited places in almost all the United States and during trips that probably lasted several weeks.
The three maps published here record the known locations of slides taken by J. B. Jackson in 1974, 1976 and 1977, and thus the possible routes he followed. A satellite night view of the United States constitute their background and also permit to estimate the urban character of the countries where J. B. Jackson photographed.
